Allows focus on operation in the green range with reduced CO2 emissions and efficient fuel consumption. ECO gauge Working Modes Selectable Large Digging Force When press the left knob switch which is called the one-touch power max. switch and when it is kept pressed, this function temporarily increases digging force for 8.5 seconds of operation. Maximum arm crowd force (ISO 6015): 218 kn (22.2 t) 233 kn (23.8 t) (With Power Max.) Maximum bucket digging force (ISO 6015): 259 kn (26.4 t) 278 kn (28.3 t) (With Power Max.) Measured with Power Max. function, 3380 mm arm and ISO 6015 rating. 7 % UP 7 % UP The excavator is equipped with five working modes (P, E, L, B and ATT mode). Each mode is designed to match engine speed and pump output to the application. This provides the flexibility to match equipment performance to the job at hand. Working Mode Application Advantage P E L B Power mode Economy mode Lifting mode Breaker mode Maximum production/power Fast cycle times Good cycle times Better fuel economy Suitable attachment speed Lifting capacity is increased 7% by raising hydraulic pressure. Optimum engine rpm, hydraulic flow One-touch power max. switch Smooth Loading Operation Two return hoses improve hydraulic performance. In the arm out function, a portion of the oil is returned directly to the tank providing smooth operation. Return hoses ATT Attachment mode Optimum engine rpm, hydraulic flow, 2 way Two-mode Setting for Boom Variable Track Gauge (Optional) Lateral stability is significantly improved when operating with the gauge extended. Lateral stability is increased by 30% (Compared with the fixed gauge version). With trackframes retracted, overall width complies with many local transportation regulations. Smooth mode provides easy operation for gathering blasted rock or scraping down operation. When maximum digging force is needed, switch to Power mode for more effective excavating. Smooth mode Boom floats upward, reducing lifting of machine front. This facilitates gathering blasted rock and scraping down operations. Power mode Boom pushing force is increased, ditch digging and box digging operation on hard ground are improved. 5
